This invention relates to srcompressorl 'and particularly pertains to improvements inth'ef typef of'compressors'especially adapted for*v use-'ineompressing airA andV other gases and of" thef character embodying a; pluralityfof radially disposedfcylind'ers lwith 'reciprocal pistons ltherein actuated by an' eccentric,v

Anobject of the invention isto provide-an improved constructionA in# the mounting of thecompressor cylinders to-l facilitate assen1 ,lolageandA 'removal and "replacementlr thereof-.-

Another obj ect@ is to' providey an' eifectivef means-'for distribnting'lubricant to thefinternal; operating part-sV4 of the compressor whereby the latter may' be properly' lubricated Vwithl `the "compressor cylinders *arranged vertically.'

' Another; object is jto provide-the `compres:`

sor with an arrangement of anti-frictionl bearings so as to reduce friction and minimizewear on the operating parts;

With the forego-ingrobjects in view with such other objects and Yadvantages7^ as maysubsequently appear., the invention resides in the parts. and:` inv the, combination, constructionandarran'gement of :parts as hereinafter described and claimed, and illustrated in the accompanying drawings in which- Fig. 1, is a view of the compressor as seen in side elevation with parts broken away.

Referring to the drawings more specifically 5 indicates anannular housing fitted with end plates 6 and7 carrying bearings 8 and 9 in which is revolubly mounted a drive shaft 10. Encircling the housing eccentric therewith isv an annulus 11 lformed with a plurality of radially extending apertures 12 through which are passed cylinders 13 to position the latter with their inner ends project-ing into radially extending openings 14 in the housing 5 leading 'to an' internal annular channel l14 in the latter; the` cylinders 13 being put in place by insertion through the outer ends ofthe apertures 12 and openings 14 and brought to a seated position on shoulders 15 provided at the innery ends of the openings 14. When put in place the outer end of a cylinder will be spaced inwardly from the outer periphery of the annulus 11 as shown in Fig. 2, whereupon a disc 16 formed with openings 17 is seatedy on the outer end 0fy the cylinder 13 whichj disc Vcarriesfonl its upper aceja thin-metal out'- wa-rdly-Y opening' disc-valve' 18 whichnormal- 1y"closesffth'e openings 17.

The outer periphery of the ring 34 is formed with a continuous channel 36 from which vleads to inner perimeter of the ring a series of perforations 36', and leading throughv the annulus 11 and communicating with the channel .14 in the housing 5 is a lubricant feed pipe 37 the innerI end of and the communicating perforations and on rotation of the ring 34'be delivered to the .i

several bearings.

Each piston 36 is formed in its outer end wall with openings v38 and which are normally closed by an outwardly opening discvalve 39, carried by the piston.

' In the operation of the invention rotation of the drivel shaft 10v operates through the eccentric 33 in cooperation `of the oating ring 34 to eiect reciprocation of the pistons 26, which act ontheir'outer strokes to force air previously trapped in the outer portion of the cylinders 13 throughv the openings 17 past the valve 18 and through the check valve-23 into the manifold 24 from whence the air thus formed under pressure may be ports 4:0k through which air is delivered to the interior of the housing 5 sothat on inward strokes of the piston 26 air will be caused to flow through the tubular stem 27 and be delivered through the piston into the compression spaces in the outer ends of the cylinders 13. This maintains a flow of' air through .the housing which tends to serve as a. cooling medium.

We claim: N ,Y

l. In a compressor an annular housing formed with a-plurality of radial openings, an annulus encircling said housing formed witliradial apertures, cylinders having their inner ends seating in the openings of the housing and their outer ends extending into the. apertures ofthe annulus, said cylinders terminating short ofthe outer ends of said apertures, valve carrying discs seating on the outer ends oflsaid cylinders, .sleeves threaded into the apertures beyond the outer ends of said cylinders maintaining said discsv and cylinders seated, reciprocal pistons in said cylinders, a .drive shaft carried by said housing. and means actuated by said shaft for operating said pistons.

Q .In a compressor, an annular housing, an annulus encircling saidl housing and spaced therefrom formed with a series of radial apertures, cylinders extending partly through said apertures having their inner ends seating in openingsformed in the housing sleeves screwing intosaid apertures and bearing against the outer ends of said cylin'- ders to hold the'latter in place, a valve at the upper end of each cylinder. reciprocal --hou-sing through the'pistons.

3. In a compressor, a series of radial' cylinders, reciprocal pistons in said cylinders, stems on said piston, anti-friction rollers on said stems, a floating ring seating on said roller-s, ya second ring concentricavith said fioating ring on whichsaid rollers-bean an eccentric, and anti-frictionrollers interposed between said eccentricand the last named ring, and means embodied in said floating ring whereby lubricant delivered to thefouter periphery ofthe latter will be distributed to said rollers.

4. In a compressor, aseries of radial cylind-ers, reciprocal pistons in said cylinders, stems on said pistons', antrfriction rollers on said stems, a floating ring seating onsaid rollers, a second ring concentricfwith said floating` ring on whichV sai'd rollers bear, an

eccentric, anti-friction rollersl interposed be'- tweensaid eccentric and the last named ring,l said floating ring being formedwith a con` tinuous channel on its outer periphery and having perforations leading to theinterior thereof, and means for delivering lubricant to said channel.

v In testimony whereof, we have atlixedoury signatures.
